To'czZZ whom it may concern Be it known that I, GEORGE B. GARDNER, of Haverhill, county of Essex, State of Massachusetts, have invented an Improvement in Heel-Part Shoe-Turning Machines,

of which the following is a specification.

This invention relates to certain improve ments in machines for turning the heel portion of turn shoes which have been sewed about the heel, and more particularly it relates to certain improvements in the heel turning devices shown in my prior Patent #797,802, dated August 22, 1905.

The heel turning device shown in said prior patent comprises three depending turning fingers, which are adapted to extend into the shoe before it'is turned, and a sole engaging head which is adapted to be moved between the fingers. V

In said prior device the action of drawing the upper sharply about the ends of these fingers causes an excessive amount of friction between the upper andsaid fingers, particularly at the middle of the back of the shoe, and, as the force required to overcome this friction and the force required to bend the upper,-as it is turned, is all transmitted to the sole by the head, the strain placed on the upper and stitches is excessive and therefore objectionable.

The object of the present invention is to improve the heel turning device of said prior patent, so as to relieve the strain upon the upper and stitches, and further to improve the machine of said patent so as to facilitate the turning operation. I accomplish this object by the means shown in the accompan in drawin which illustrates the best form of the invention at present known to me.

In the drawing Figure l is a side elevation of a shoe turning machine provided with my invention. Fig. 2 is a front view of the main operating parts of the machine. Figs. 3 and 4 are sectional views on the line aa of Fig. 1, showing the parts in different positions. Figs. 5, 6 and 7 are enlarged sectional views-on the line Z b of Fig. 2, showing the parts in different positions. Fig. 8 isv a detail sectional view on the line 0-0 of Fig. 5. Fig. 9 is a detail view on the line dd of Fig. 5. Fig. 10 is a detail view of the front side of the main upper or counter holding finger. Fig. 11 is an end view of said finger. Fig. 12 is a detail View, partly in section, of the end portion of said finger. Fig. 13 is a detail-sectional View, on an enlar ed scale, taken at the line e-e of Fig. 12. Fig. 14: is a detail sectional view on the line f; of Fig. 5. Fig. 15 is a plan view of the sole-engaging head.

As shown in the drawing, the main frame 1 is provided with a boss 2, in which a rod 3 is adapted to reciprocate vertically, said rod having a head 4: on its upper end, the upper side of which is provided with a soleengaging face having teeth 4* thereon adjacent the front edge thereof. Suitable means for raising and lowering said head may be provided, such as the means shown in said prior patent, or the power driven means indicated in the drawing, which comprises a main shaft 5 having a crank 6 which is connected to a connecting rod 7, said rod 7 being connected to a lever 8 and said lever 8 being connected to the lower end of rod 3 by a link 9, so that when the shaft is rotated in the direction of the arrow in Fig. 1 said rod 3 will be lifted. A returning spring 10 for the shaft is indicated.

A standard 11 is mounted on the frame and a horizontally projecting bracket 12 is mounted thereon, said bracket extending forwardly and having its front end portion 12' obliquely disposed to the horizontal. A turning finger 13 is pivotally connected by a pin 13 to the under side of said bracket end portion 12 and extends at an angle of about 45? to the perpendicular to within a short distance of the path of said head 4. The pin 13 is arranged to permit a certain swinging movement of said finger 13, shoulders 13, 13 on said finger, at its base, limiting the movement thereof on said pin in both directions. Said finger is normally held by gravity in the position of Figs. 5 and 7, in which position the front shoulder 13' bears against the under side of said bracket 12. Said finger 13 is disposed to engage the heel portion of the upper at the middle of the back thereof, and, as in my said prior patent, is provided with three antifriction rolls 14:, 15 and 16, at its lower end. In my said prior patent, however, said rolls were shown as mounted to rotate about the same axis, while in the present instance the end rolls are arranged to rotate about axes which are at an angle to the axis of the middle roll. With the arrangement of said prior patent, the ends of the side rolls were pressed against the counter with much greater force than the sides thereof, thereby causing undue strain on such portions of the shoe and greatly increasing the difficulty of turning.

According to my present invention the end rolls are set at such an angle with relation to the middle roll that the longitudinal contour of the surfaces of said rolls follows approximately the normal curve of the counter so that the strain, or friction, of the rolls on the counter is practically no greater at one point than at another, and the counter is not pulled out of shape or damaged. The manner in which these rolls are preferably mounted on the end of the finger 13 may be described as follows. A

pair of hangers 17 and 13 are provided,

which are adapted to be set into slots in the end of the finger, and to be secured therein by a pin 19. The side faces of said hangers are arranged obliquely with relation to each other and a pair of bearing pins 20 and 21 are fixed in said hangers, said pins having heads at the outer ends thereof and being passed through the tapering rolls 14 and 16 before they are fixed in said hangers. The ends of the middle pin 22, on which roll 15 is mounted, are inserted in recesses in the pivots 20 and 21, and when held in this position, the hangers are inserted in the slots and secured by pin 19. As it is desirable to provide for wide variations in sizes of the shoes, said hangers are preferably mounted in an end piece 23 which is provided with arms 23, which are adapted to be removably secured in corresponding slots in the body of finger 13, so that other end pieces having rolls of different sizes may be attached.

A pair of depending fingers 24 and 25 are adjustably mounted in transversely extending horizontal slots in the under side of the bracket 12, said fingers extending convergently and terminating at some distance above the lower end of the finger 13. An, adjusting screw 26 is swiveled in a lug 12 on the, lower side of bracket 12 and is provided with right and left screw threads at the oppositeends thereof, which are screwed into said fingers 24 and 25 at their base portions, whereby said fingers may be adjusted toward and from each other, vaccording to variations in the width of the shoes, by turning said screw 26.

An upper engaging device'or dog 27 is mounted to slide on the outer or front side of the finger 13, in a longitudinal dovetail groove formed in said finger, as shown in Fig. 8. The lower side of said dog 27 is provided with a concave upper engaging face 27", which extends obliquely upward from the inner side thereof, so that said face and the surface of said finger on which said dog is mounted are as nearly continuous as practicable, and then outwardly and downwardly, as shown. A link 28 is connected by a pivot 29 at its lower end to the dog 27, and at its upper end by pivot 30 to the front end of a lever 31, the latter ex: tending rearwardly through a slot 13, formedthrough the middle portion of said finger 13, see Fig. 10, in an approximately horizontal direction, when in its normal position, said lever being located in and adapted to swing in the vertical plane midway between said fingers 2 1 and 25. The lever 31 is pivoted at an intermediate point by pin 31 to the lower end of av rod 32, which is mounted to slide longitudinally in the bracket 12 in a position nearly parallel to the finger 13, and in the vertical plane of said lever 31, said rod 32 being held in a depressed position by means of a pair of springs 33 which are connected to a stoppin 34 in the rod 32, and act to draw said pin against the end of a guiding boss 12 on the bracket 12 through which the rod passes. An operating finger 35 is mounted to slide in the bracket 12 in vertical alinement with the head 4:, and also in the vertical plane of lever 31, said finger 35 depending approximately to the level of the friction rolls on the end of finger 13, and having sole-engaging teeth at its lowerend which are disposed directly over the teeth a of the head 4, closely adjacent the frontwhere said lever is engaged by the finger 35,

so that the downward movement of said dog 27 will be somewhat more rapid than the upward movement of the head 4, due allowance also being made for the fact that the movement of the dog is oblique to the lever 31, while the movement of the finger 35 is nearly perpendicular thereto. A shank supporting pair of springs 36 are connected to a stop pin 36. in the upper end of said finger 35 and are also connected to the bracket 12 so that said pin is normally held thereby against the upper end of a guiding boss 12 through which said finger 35 passes.

A pair of turning fingers 37 and 38 are mounted to slide longitudinally in dovetail grooves formed on the outer sides of said fingers 24 and 25, and said fingers 37 and 38 are connected at their upper ends, by means of links 39 and 39 to the outer ends of levers 40 and 41, respectively, said levers 40 and 41 being pivoted at their middle portionsupon links 42 and 43 respectively, the latter being pivotally mounted at their lower ends on the upper side of the bracket 12. r The inner ends of said levers 40 and 41 are both pivotally connected to a head 44 on the upper end of a rod 45, said rod being mounted to slide vertically in the bracket 12 in the same vertical plane as that of the lever 31. The lower end of said rod 45 is provided with a head 45 and a spring 46 is interposed between said head and the under side of said bracket 12, so that said spring, acting against said head 45 will draw the head 44 against the upper side of the bracket and hold the fingers 37 and 38 in such a position that the ends thereof are practically even with the ends of the fingers 24 and 25, as shown in Fig. 4.

A shank supporting arm 47 is ad justably mounted in a dovetail slot on the upper side of the head 4, and extends rearwardly therefrom in a slightly upwardly inclined direction. Preferably the inclination of the arm is such that it extends approximately at right angles to the turning finger 13, thus assisting in supporting the shoe in its inclined working position hereinafter referred to. Said arm may be provided with an enlarged end portion 47 of somewhat greater width than the shank portion thereof.

The operation of my device is substantially as follows: A shoe which has been sewed about the heel inside out is placed on the upper holding fingers 13, 24 and 25 with the middle of its heel portion at the outer side of the finger 13, and the shoe bottom extending obliquely upward at an angle of about 45 to the path of the head 4, in which position the lower ends of the fingers 24 and 25 touch the bottom of the sole, as indicated in Fig. 1. In this position the face 27 of the dog 27 is held closely adjacent the upper edge of the heel portion of the shoe upper, at the middle thereof and, preferably, so that the lip formed at the lower inner end of said face, or the portion next the finger 13, extends to a slight extent beneath said portion of the upper.

In turning the heel part of a shoe to the best advantage and with the least strain on the shoe, the first operation to be performed is to press the portion thereof at the point where the sole is joined to the upper inwardly in a line which approximately bisects the angle between the sole and the back of the counter. The head 4 is arranged to move so that its raised teeth will engage the shoe with the sole seam at the middle of the back, and, as the shoe is held with its bottom at about 45 to the path of said head, it will be apparent that when the head is raised it will press the seam inward approximately in the direction of said bisecting line. It is desirable that the front edge of the head pass as closely as practicable to the rolls at the lower end of finger 13 on the up, or turning movement, but, with the device of said prior patent I have found that if the finger which corresponds to finger 13 is set as closely as desirable for the no movement of the head on the down movement the teeth on the head are liable to catch in the lining of the shoe and the counter is liable to become bound between the head and the sides or rolls of the finger, with the result that the shoe is damaged. With my present construction the arrangement is such that when the finger 13 is swung upward to its fullest extent the space between the rolls and the front side of the head will be just sufficient to permit the back of the shoe to be drawn therebetween, while when the finger has dropped back to its normal position the space therebetween is much wider and sufiicient to prevent all possibility of the shoe back being caught therebetween. In operation, when the head engages the seam and presses it inwardly the upward pressure immediately causes the finger 13 to be swung upward and, therefore, its end to be swung toward the path of the head, and the finger will be held in this position during the remainder of the turning operation. When the operation is finished, or as soon as the head begins to move downward, the finger 13 will swing back to its normal position by gravity, increasing the space between the rolls and the path of the plunger to the necessary extent. A further advantage of the oblique arrangement of finger 13 to the path of the plunger is that there is no possibility of binding between the finger and the head after the latter has passed the rolls, but the principal advantage of this arrangement is that it holds the shoe in the most advantageous position for turning.

When the head 4 is raised and the turning operation begun, by pressing the sole upwardly, as shown in Fig. 5, as soon as the sole is raised to an appreciable extent its upper side is pressed against the lower end of finger 35 causing the latter to be forced upwardly, so that it swings the lever 31 and moves the dog 27 downwardly, into engage ment with the edge portion of the upper. As the dog 27 is moved downwardly, it acts to push down the back of the counter portion of the shoe, and, as this movement is slightly faster than the up movement of the head, it tends to push it down slightly faster than the head 4 tends to pull it up by forcing up, the sole and drawing said counter portion about the friction rolls. By this means the strain which must be placed on the upper by the head to draw the upper about the lower end of the finger 13, will be reduced to a minimum. In other words, practically all the pull which must be necessarily exerted upon the upper, by means of the upward pressure on the sole, is a pull sufiicient to bend the upper about the antifriction rolls as it is drawn. up between the fin ers. Durin the first aart of this moveb C i ment the portion of the upper which pro-- jects above the upper edge of the counter will be rolled outwardly, as indicated in Fig. 6, but as soon as the dog firmly engages the upper edge of the counter the whole back part of the heel portion will be positively pushed down slightly faster than it would otherwise be drawn down by the head. This movement is continued until the dog 27 is moved into engagement with the end of the dovetail groove in which it slides, as shown in Fig. 7, so that further upward movement of the finger 35, which would tend to move the dog below this point, will be permitted by the yielding of the rod 32 against the action of its springs 33.

When the heel portion of the shoe is partially turned as shown in Fig. 6, the arm 47, which supports the sole in the shank portion thereof, brings the sole into engagement with the head at the lower end of the sliding rod 4L5, and further upward movement of the head 4 causes said rod l5 to be forced upwardly, raising the inner ends of the levers L0 and ll and forcing downwardly the fingers 37 and 38. The supporting fingers 2a and 25 are set so that when the fingers 37 and 38 are forced downwardly, they will engage the upper adjacent the sole, and push it down as the sole is pushed up by the head, causing the upper to be drawn about the ends of said fingers and thus turned. By this means the turning operation is performed to the best advantage with a minimum strain on the shoe, that is, the middle of the counter portion is first pushed in and partly turned and then. as the turning of this portion of the shoe is finished, the sides of the counter portion are quickly pushed down by fingers 37 and 38, the downward movement of said fingers making it unnecessary to raise the head beyond a point at which the turning operation of the middle of the counter portion is complete. In this connection it will be observed that it is necessary to have the lower ends of the side fingers arranged to terminate at a much higher point than that of the middle finger, when in their normal position, to permit the shoe to be held in the inclined position of Fig. 1.

After the heel portion is turned, before the head 4 is lowered, and while the sole is securely clamped against the head by the rods 35 and 45, the sole of the shoe may be most conveniently bent across the ball, or broken, as it is usually termed, prelimi nary to the turning operation of the fore part, as indicated in Fig. 7, the upper being drawn down so that the shoe is held in the bent position shown, in which position it may be conveniently transferred to the forepart turning apparatus which is preferably operated in conjunction with the apparatus above described.

It will be understood that While the de.

vice may be operated most conveniently in the position shown, the terms upwardly and downwardly, and terms of similar import, as used in the claims, are merely relative.
